Title: Inhibition of Yeast Glycolysis Abstract: The purpose of this experiment was to study carbon dioxide emissions from yeast‚ as well as their respiratory rate and to use that data to study how glycolysis inhibitors affect the respiratory rate. In our experiment‚ we tested how 8.75% glucose + 1.25% NaCl‚ 8.75% glucose + 1.25% glucose-6-phosphate‚ 8.75% glucose + 1.25% citric acid‚ and yeast solution‚ all mixed with distilled water‚ affect carbon dioxide volumes and respiratory rate. Our results

* Would yeast produce more carbon dioxide with the presence of sugar at room temperature or in an incubator? | -Observing Cellular respiration in yeast cells. | Yeast Lab Background Information: Yeast is a tiny unicellular fungus that obtains energy from outside sources (a heterotroph) mostly sugars in order to grow and reproduce. Yeast is often used in bread dough to make the dough rise. With the presence of oxygen a yeast cell creates energy by performing cellular respiration and

Yeast Population Dynamics Lab How Environmental Factors Affect a Yeast Population’s Ability to Reproduce OBJECTIVE The objective of this experiment is to emphasize the influence that limiting factors have on a population. This lab tests yeast‚ a common component in baking‚ against two environmental factors (changes in temperature or concentration) to see what effect these have on the population dynamics of the yeast over a period of 72 hours. There are two sections of tests included in this

Yeats Fermentation Lab Investigative Question: How does the sugar concentration affect the fermentation of yeast? Hypothesis: The percentage of sugar in a solution is directly proportional to the amount of produced CO2‚ as a result of Yeast fermentation. Data table: Amount of CO2 measured in cm. (Bubble length) | Trial | Percentage of sugar in solution | | | 0% | 5% | 10% | 15% | 20% | | 1 | 0 | 0.5 | 0.5 | 0.3 | 3.1 | | 2 | 0 | 0.3 | 1.3 | 0.4 | 5 | | 3 | 0 | 0.2 |

to move than an athletic shoe. (8 points) If you wanted the athletic shoe to slide faster on a surface‚ what might you do to the shoe? Provide at least two ways to make the shoe slide faster‚ and explain in terms of the force of friction and the coefficient of friction. Answer: To make a shoe slide faster‚ you might decrease the weight of the shoe. ----------------------- |Name: Jernero

Comparing the Rate of Fermentation of Yeast in Solutions with Different Concentrations of Glucose Brandon Bosley BIO 121 11/19/2013 Introduction: In our lab this week we tried to see how different amounts of substrates affect our organism‚ yeast‚ in its fermentation process. Yeast (Saccharomyces cerevisiae) is an organism that is cultured for the cells themselves‚ as well as the end products that they produce during fermentation. Yeasts are commonly known for the ethanol fermentation due
